The agency calls GTL's long-term future "uncertain" and says it expects the production of GTL fuel to total 650,000 barrels per day by 2030 -- just 0.6% of the projected global oil output for that year.

Sorrentino and MPS Entertainment trademarked his "Jersey Shore" nickname, "The Situation" and catchphrase "GTL" -- an acronym for gym, tan, laundry -- in 2009, after the first season of MTV's "Jersey Shore" became widely popular.
